Boilogy 1-3 Mindmap
- Biology 1 - Characteristics of living organism
- Biology - Study of living organisms and their enviorment
- MRS GREEN
- Movement
- Respiration
- Sensitivity
- Growth
- Reproduction
- Excretion
- Nutrition
- Give us energy and tissue repair
- Absorbed and assimilated
- Autotrophs ( Plants + Algae)
- Heterotrophs (Animals)
- Saprotroph (Bacteria + Fungi)
- Needed for 'species' to survive
- A group of organisms capable and producing fertile offspring
- Asexual reproduction - Gametes not used
- Sexual reproduction - Joining gametes
- Grow as number of its cells increase
- Glucose + Oxygen = CO2 + H2O (+ Energy)
- Animals move to obtain food or find mates - Plants can also move (Mimusa Pudica)
- Internal movements of Organelles and fluids, and external movement (Locomotion)
- Some animals are sessile, or move very little
- Living things response to changes in the enviorment
- e.g. Plant grow toward light
- Composed of cells
- Levels of organization
- Adaptation to enviorment (Evolution)
- Maintain homeostasis (pH,Temp., salinity)
- Bionomial Nomenclature
- Carolus Von Linnaeus - Swedish
- Genus - Capitalized, underlined or Italicized
- Species - Lower case, underlined or italicized
- Taxonomic categories
- Kingdom
- Phylum
- Class
- Order
- Familiy
- Genus
- Species
- Monera (Bacteria), Protista (single cells organism), Plantae, Fungi, Animalia
- Biology 2 - Cells
- Living organisms are made up of cells
- Animal cells
- Cell membrane that surround nucleus and cytoplasm
- Nucleus contains chormosomes
- Red Blood Cell - Biconcave, no nucleus, Haemoglobin
- Plant cell
- Vacuole, filled with cell sap - Cellulose - Starch grains storage - Chloroplast
- Osmosis - Diffusion in water, plants take in water by osmosis
- Water Potential Gradient
- When WPG is lower in the cell than the surrounding, it can absorb water
- WPG in cells are higher in leaves than roots
- 1665, Robert Hooke observed bark cells using simple microscope
- 1675, Anton van Leeuwenhoek first observed living cell, RBC
- Cells are usually 10-100um.
- 1mm = 1000um
- Biology 3 - Enzymes
- Proteins that are biological catalysts
- Too much heat can denature, and too little heat will make it slower to act
- Extreme pH will denature the enzymes
- Denature - Change of active site so it can no longer take in the substrate
